re: the 19mm (3/4" [wink]) holes, their existing project center uses 3/4" dog holes, so compatibility there was probably a concern for them.
But the table had me thinking of what the practicality would be of reaming the holes to 20mm. A quick google search shows prices of 50-80 USD for the tool, so not much benefit vs just buying an MFT. I don't currently own an MFT, but I do have a DeWalt work table which uses 20mm dog holes, so I am partially invested in the 20mm standard already.
